I have tpfc installed on a t420, Windows 7 (modified .ini file) and it works nicely for days or weeks. One day
when booting up the sensor in the taskbar shows "0" and "xc3" - all of the sensors show "n/a". I tried stopping/
starting the program (also with the original .ini file), which does not help. Reinstalling the program currently
does not work either - no sensor information is read out (reinstalling the nth time sometimes helps).
ps: I did not install any new software in the period when tpfc stopped working
